Problems solved by technology

[0002] The multimedia information transmission in the existing elevators mainly uses hard disks and CDs to play, and now there is a newer form of broadcasting, but none of them use the local area network to transmit information. The effect is better, it is more timely and easy to maintain
However, due to the multiple reciprocating movements of the elevator every day, the conventional network cable cannot withstand its harsh use environment and methods

Embodiment Construction

[0007] as attached figure 1 As shown, the elevator multimedia network cable of the present invention includes a special hybrid cable for elevator room combination of network wire 10 and power wire 20 .

[0008] Among them, the network cable 10 is a high-density braided layer 103 added to the periphery of a high-speed data cable composed of a core wire 101 composed of a stranded conductor plus an insulating layer and a cable inner sheath 102, thereby forming a super-category 5 network cable. The network cable meets the electrical performance requirements for stranded Category 5e cables in EIA / TIA-568B, and can meet the requirements for stranded Category 5e network cables. A reinforcing member 30 composed of Kevlar fiber and a sheath is arranged in the middle of the above-mentioned network cable 10 and power cable 20, the three are combined into one, and finally a layer of extruded outer sheath 40 is covered, thus forming a The special composite cable for elevator rooms of the ...

Abstract

The invention discloses multimedia combination cable used in lift comprising data communication symmetrical cable and high wove layer covering the outer layer of said data cable; a powder cord; a reinforcing element arranged between said data cable and powder cord; and a sheath arranged in the outer layer of said data cable, powder cord and reinforcing element. The inventive data communication symmetrical cable arranges high density wove layer which can prevent outer electromagnetic interference effective, ensure the accuracy of data communication; the reinforcing element formed by Kafra fiber with inner layer can improve the intensity; and each conductor formed by hinge line improves the softness of line. Said invention realizes the use of custom high speed data communication cable in lift, with high density metal shield layer, while using the Kafra fiber instead of the normal steel reinforcement element, and combining the other cables to improve the flexibility of arrangement of cable.

Description

technical field [0001] The present application relates to a cable, in particular to a combined cable with a shielded data communication symmetrical cable and a power cord in an elevator room for high-performance data transmission. Background technique [0002] The multimedia information transmission in the existing elevators mainly uses hard disks and CDs to play, and now there are newer forms of broadcasting, but none of them use the LAN information transmission effect, which is more timely and easy to maintain. However, due to the multiple reciprocating movements of the elevator every day, the conventional network cable cannot withstand its harsh use environment and method. Contents of the invention [0003] In view of the above problems, the present invention proposes a combined cable composed of a shielded data communication symmetrical cable, a power cord and a sheath, and a high-density braided layer is added outside the network cable to effectively prevent external ...
